Chimney Flashing Repair and Cleaning for Leaking Roof in Greenford

by

Chimney Flashing Repair and Cleaning – Perimeade Road, Greenford

A small leak in the sitting room upstairs from the roof, which is underneath the chimney. Checked the loft and noticed some water on the glass fibreglass insulation. Might be a problem with lead flashing around the chimney. Needs cleaning too as there’s vegetation growing on the chimney.

Understanding the Issue

Leaks around chimneys are often caused by deteriorated or improperly installed lead flashing. Water can seep into the structure, leading to damp insulation and potential interior damage. Additionally, vegetation growth on chimneys can retain moisture and contribute to further deterioration of the brickwork and mortar.

Steps to Repair the Chimney Flashing and Clean the Chimney

A comprehensive approach is required to ensure long-term watertightness and chimney stability:

  1. Inspection:
    • Examine the chimney flashing for cracks, gaps, or corrosion.
    • Assess the surrounding roof tiles and mortar joints for signs of deterioration.
    • Inspect the attic for further signs of moisture intrusion.
  2. Vegetation Removal:
    • Safely remove moss, algae, and plant growth from the chimney using specialised tools.
    • Apply an anti-moss treatment to prevent future regrowth.
  3. Flashing Repair or Replacement:
    • Remove damaged lead flashing and replace it with high-grade Code 4 or Code 5 lead flashing.
    • Secure the new flashing using appropriate fixings and lead sealant to create a waterproof barrier.
    • Ensure correct overlapping and integration with the roof tiles to prevent further leaks.
  4. Repointing Chimney Brickwork (If Needed):
    • Repoint any deteriorated mortar joints to reinforce structural integrity.
    • Apply a weatherproof sealant to protect against future moisture damage.
  5. Final Inspection and Testing:
    • Check for proper drainage and conduct a controlled water test to ensure no further leaks.

Cost Considerations

The cost of repairing chimney flashing and cleaning in Greenford typically ranges from £500 to £1,500, depending on:

  • The extent of the flashing damage and whether a full replacement is required.
  • Access challenges (scaffolding may be needed for a 2nd-floor roof).
  • Additional work such as repointing or roof tile repairs.

Benefits of Chimney Flashing Repair and Cleaning

Addressing the issue promptly offers several benefits:

  • Prevents Further Water Damage: Protects the interior from dampness and mould growth.
  • Enhances Roof Longevity: Proper flashing prevents water from seeping under the roof structure.
  • Improves Aesthetics: Removing vegetation and cleaning the chimney enhances curb appeal.
  • Boosts Energy Efficiency: A watertight roof reduces heat loss and improves insulation performance.

Preventative Maintenance Tips

To prevent future chimney leaks and vegetation regrowth, consider the following:

  • Regular Inspections: Schedule annual roof and chimney inspections.
  • Gutter Maintenance: Ensure proper drainage to prevent water buildup near the chimney.
  • Moss Prevention Treatments: Apply protective coatings to inhibit moss growth.

Preparing for the Repair

Homeowners can help prepare for the repair process by:

  • Clearing access points for scaffolding or ladders.
  • Checking for additional leaks inside the property.
  • Discussing material preferences with the contractor to match the existing roof style.
